Seattle’s Building Energy Benchmarking and Reporting Program (SMC 22.920) requires owners of non-residential and multifamily buildings (20,000 square feet or larger) to track energy performance and annually report to the City of Seattle. Buildings account for 33% of Seattle's core emissions. The benchmarking policy supports Seattle's goals to reduce energy use and greenhouse gas emissions from existing buildings. In 2013, the City of Seattle adopted a Climate Action Plan to achieve zero net greenhouse gas (GHG) emissions by 2050. Annual benchmarking, reporting and disclosing of building performance are foundational elements of creating more market value for energy efficiency.
Per Ordinance (125000), starting with 2015 energy use performance reporting, the City of Seattle will make the data for all building 20,000 SF and larger available annually. This update to the benchmarking mandate was passed by Seattle City Council on February 29, 2016.
